Organic chemistry problem
« on: August 10, 2011, 11:40:39 AM »
Hi,

My question is about the reaction in the picture.



I don't know sure what the answer is. I thought that maybe water would split off, but I'm not sure.

I hope you could help me please.

Decarboxylation is very favorable entropically, which means ΔS is positive. Since ΔG = ΔH - TΔS, once the temperature is high enough to overcome the ΔH term (barrier to decarboxylation), the molecule loses CO2.
